Experimental Research on Hot Air for Capsicum Continuous Drying
Drying capsicum on continuous dryer and research the temperature of hot air influence on capsicum , in order to keep the capsicum quality ,improve the drying rate , reduce the drying time , save the cost of drying .Changing the tem-perature of hot air and measure weight , dry uniformity and drying rate to compare the change characteristics .The experi-mental results show that , with the rise of air temperature the drying rate was accelerated , surface brightness and red de-gree was accelerated , while dry uniformity was reduced .Considered the drying efficiency and quality , 60℃and 65℃of temperature can ensure capsicum color and drying uniformity , and can achieve good drying rate .
